Wrong URL for multisite media upload

Reported by @pmgarman

Image uploaded on a multisite install has the wrong URL.

ymir.yml config used for example:

id: 810
name: garman-dev
type: bedrock
environments:
  staging:
    architecture: arm64
    php: 8.1
    cache: ymir
    cdn:
      caching: assets
    cron: false
    warmup: false
    database:
      server: ymir
      name: garman_dev_staging
    domain:
      - staging.garman.dev
      - '*.staging.garman.dev'
    build:
      commands:
        - 'sh ./build.sh'
      include:
        - web/app/plugins/cloudflare/config.json
        - web/app/plugins/cloudflare/composer.json
        - web/app/plugins/query-monitor/assets

Ok, so I suck and failed to notice the caching: assets. You need caching: enabled. However, there's still an issue that, with multisite, the media URL is always the first domain mapped to a project which isn't normal behaviour for WordPress.
